Liquid crystal forehead thermometer. A liquid crystal thermometer, temperature strip or plastic strip thermometer is a type of thermometer that contains heat-sensitive (thermochromic) liquid crystals in a plastic strip that change colour to indicate different temperatures. [1] Liquid crystals possess the mechanical properties of a liquid, but ...
Liquid crystal color transitions are used on many aquarium and pool thermometers as well as on thermometers for infants or baths. [83] Other liquid crystal materials change color when stretched or stressed. Thus, liquid crystal sheets are often used in industry to look for hot spots, map heat flow, measure stress distribution patterns, and so on.
Liquid crystals used in dyes and inks often come microencapsulated, in the form of suspension. Liquid crystals are used in applications where the color change has to be accurately defined. They find applications in thermometers for room, refrigerator, aquarium, and medical use, and in indicators of level of propane in tanks.
Forehead thermometer is an example of a liquid crystal thermometer. Rectal and oral thermometers have typically been mercury but have since largely been superseded by NTC thermistors with a digital readout. [59] Various thermometric techniques have been used throughout history such as the Galileo thermometer to thermal imaging. [45]
